Definitions
- the present invention relates to the inspection of large containers by means of x-ray radiation, and more particularly to the x-ray inspection of cargo containers by means of transmitted and back scattered radiation.
- Non-intrusive inspection is typically non-destructive and can usually be accomplished faster than intrusive inspection, thereby increasing productivity of inspectors. Increased productivity means more containers inspected and more contraband interdicted.
- x-ray imaging in its many forms has been a proven technology capable of detecting a variety of contraband.
- X-ray systems have been based on transmission imaging in any of a variety of implementations: cone-beam (fluoroscopes), fanbeam, flying-spot, multi-projection configurations; dual-energy imaging; computed tomography; as well as on imaging incorporating the detection of x-ray radiation scattered in various directions.
- x-ray imaging systems for contraband detection have operated within the source-energy range of 70 keV to 160 keV. Since the penetrating power of these sources is limited, inspection is limited to relatively small parcels and containers. A few large, expensive, high-energy transmission imaging systems have also been built for the inspection of large containers or vehicles. These systems typically operate within the range of 6 MeV to 12 MeV, require heavily-shielded, fixed installations, and provide no means to distinguish organic materials.
- the current invention extends the role of inspection by penetrating radiation to encompass large containers and over-the-road vehicles, and at the same time retains the advantages of discriminating among materials as provided by backward, forward, or sideward scatter imaging.
- the invention provides a device for inspecting a cargo container with penetrating radiation.
- the device of this embodiment has a bed moveable along a first direction having a horizontal component, a source of penetrating radiation, mounted on the bed, for providing a beam, a motorized drive for moving the bed in the first direction, and at least one detector mounted on the bed and having a signal output so that the beam is caused to traverse the cargo container as the bed is moved and each detector provides a signal for characterizing the cargo container and any contents of the cargo container.
- the source of penetrating radiation may be an x-ray source
- the at least one detector may be a backscatter detector, a transmission detector, a sidescatter detector, or a forward scatter detector.
- the beam may be a pencil beam scanned repeatedly along a second direction having a vertical component.
- the device also has a boom, movably linked to the bed.
- the boom has a storage position, substantially fixed with respect to the bed, and an operation position that is transverse to the first direction, as well as an end region.
- a beam catcher is attached to the end region of the boom for impeding the further passage of penetrating radiation in the second direction when the boom is in the operation position.
- the back scatter detector has upper and lower elements, the upper element being movably mounted with respect to the lower element, so that in a first position the upper element is transversely disposed with respect to the lower element and in a second position the upper element is substantially collinear with respect to the lower element.
- the source of penetrating radiation may provide a pencil beam that is scanned repeatedly over an angle of regard, the angle having an orientation with respect to the horizontal, and the device also includes a steering arrangement for steering the orientation of the angle of regard with respect to the horizontal.
- the boom may be alternatively provided, at its end region, with a transmission detector attached to respond to penetrating radiation transmitted through the container, so as to provide a signal for forming a transmission image of the container.
- the source of penetrating radiation includes an x-ray tube operating at a voltage in substantial excess of 200 kV, and may operate in a region of approximately 450 kV.
- the invention provides a method, for producing an x-ray image of a large object, utilizing a device such as described above, along with an arrangement for processing the signal from the signal output of the detector to form an image of the object.
- the invention is a scatter image of an object.
- the image is formed by (a) providing a device such as described above, then (b) using the motorized drive to move the device past an object so as to cause the object to be scanned along two dimensions; and (c) processing the signal from the signal output of the detector to form an image of the object.
- the object may, for example, be a motor vehicle having at least two pairs of wheels.
- the object may also, for example, be a trailer, a railroad car, a sea cargo container, an air cargo container, or a freight pallet.

- a “cargo container” is a receptacle for the storage or transportation of goods, and includes freight pallets as well as vehicles, whether motorized or drawn, such as automobiles, the cab and trailer of a truck, railroad cars or ship-borne containers.
- the term "cargo container,” as used herein, further includes the structures and components of the receptacle.
- the invention described herein serves to characterize materials which may be contained within a cargo container and thus not readily susceptible to visual scrutiny.
- the characteristics of a material which might be the object of non-invasive inspection and which lend themselves to detection using the device and method taught by the invention include, but are not limited to, electron density, atomic number, mass density, linear dimensions and shape. These characteristics are unveiled by taking advantage of the various physical processes by which penetrating radiation interacts with matter.
- Penetrating radiation refers to electromagnetic radiation of sufficient energy per photon to penetrate materials of interest to a substantial and useful degree and include x-rays and more energetic forms of radiation. The interaction of such radiation with matter can generally be categorized as either scattering or absorption processes.
- Both types of process remove x-ray photons from a collimated (i.e., directional) beam; scattering processes do so by deflecting photons into new directions (usually with loss of energy), while absorption processes simply remove photons from the beam.
- the total beam attenuation is described by a parameter called the mass attenuation coefficient, as commonly employed by persons skilled in the art of x-ray inspection.
- the mass attenuation coefficient is a characteristic of a particular material at a specific x-ray photon energy, and is independent of the imaging geometry. As such, it is the sum of individual coefficients (or "cross sections") for each relevant physical process, each of which varies differently with x-ray energy and with the atomic number (Z) of the interacting material.
- the scattering contribution is dominated by incoherent, or Compton scattering, and the absorption contribution is dominated by the photoelectric effect.
- the cross sections for Compton scattering and photoelectric absorption vary with both the atomic number of the material and with the energy of the x-ray photon, but in very different ways.
- the photoelectric absorption decreases very rapidly with increasing photon energy, and increases very rapidly with increasing Z of the material.
- the Compton scattering cross section changes very slowly with energy and is only weakly dependent on atomic number.
- the Compton scattering cross section 10 for a low-Z material such as heroin and the Compton scattering cross section 12 for iron are nearly identical over the energy range of interest, and show little variation with energy.
- the photoelectric cross sections 14 and 16 are very different for the two materials, and both vary rapidly with energy.
- the Compton scattering cross section 10 dominates the photoelectric cross section 14 for all x-ray energies above 20 keV.
- the photoelectric cross section 16 dominates for energies up to about 120 keV.
- the total absorption coefficient (the sum of the Compton and the photoelectric coefficients) varies by less than a factor of two for heroin but by about a factor of 13 for iron.
- image refers to any multidimensional representation, whether in tangible or otherwise perceptible form or otherwise, whereby a value of some characteristic is associated with each of a plurality of locations corresponding to dimensional coordinates of an object in physical space, though not necessarily mapped one-to-one thereonto.
- the graphic display of the spatial distribution of some feature, such as atomic number, in one or more colors constitutes an image. So, also, does an array of numbers in a computer memory or holographic medium.
- imaging refers to the rendering of a stated physical characteristic in terms of one or more images.
- Backscatter imaging in which the x-rays scattered by a material in a generally backward direction are employed offers several unique inspection capabilities and operational features.
- images can be obtained even when the object is accessible from only one side, or, the object is too thick to be penetrated radiographically.
- backscatter images effectively represent a "slice" of the object characteristic of the side nearest to the x-ray source; this image is frequently useful even when a transmission image representing the same scanned area is hopelessly confused by image clutter.
- the underlying physical phenomenon that leads to scattered radiation is the Compton effect.
- Low atomic number (low Z) materials which encompass organic materials, interact with x-rays principally by Compton scattering. Narcotic drugs, being among the densest of organic materials, tend to produce the brightest signatures in a backscatter image, as do organic explosives, making backscatter imaging a useful imaging modality for bomb or drug detection. (4) Alignment requirements of the x-ray beam with detectors or collimation devices are less exacting than for transmission imaging thereby enabling rapid deployment in a wide range of inspection scenarios.
- Compton scattering removes x-ray photons from the x-ray beam, it contributes to the attenuation map image produced by transmitted x-rays.
- a scattered photon that is removed from one beam path projection and scattered into another contributes only an unwanted background or "fog" in the transmitted x-ray image.
- the scattered background can be a serious problem, and can, in fact, dominate over the transmitted x-ray image data.
- Another method to image low-Z materials is backscatter imaging.
- the technique relies upon the direct detection of photons which have been Compton scattered. An image is created that is separate and independent of any transmission image that may be produced at the same time. Since the photoelectric absorption cross section is small for organic materials, they interact almost entirely through Compton scattering, producing relatively large scatter signatures. Metals, on the other hand, interact almost exclusively by photoelectric absorption, so that their scatter image signature is comparatively small.
- the backscatter image directly reveals organic materials such as drugs or explosives.
- Flying-spot technology makes possible the acquisition of images using detectors specifically positioned to collect the scattered x-rays.
- a thin "pencil beam" of x-rays is rapidly and repetitively swept through a source-centered, vertically-oriented "fan” of beam paths that are arranged to intercept the object under inspection.
- the object is moved at a constant, slower speed along a path perpendicular to the fan, on a horizontally moving conveyor belt for example.
- the pencil beam is made to traverse the object in point-by-point raster fashion, and the entire object is scanned as it passes through the fan plane over a period ranging from a few seconds to a few minutes depending upon the length of the object.
- the total scan time is seconds to minutes in duration
- the actual exposure time of any part of the scanned object is only the time it takes for the pencil beam to sweep across that pixel. That exposure time is typically in the range of 8 to 64 microseconds, depending on the design and the application, and yields an entrance exposure to the scanned object of only tens or hundreds of microroentgens.
- This low dose to the object also means that there is little radiation available to scatter into the environment, so the doses to operators and other bystanders is correspondingly low.
- Separate, large-area detectors are deployed adjacent to the beam plane on the x-ray source side of the scanned object, and with their active surfaces oriented toward the scanned object. These detectors need only provide a large solid angle for collection of scattered radiation; no critical alignments are required. In this location these detectors respond to x-rays which are scattered generally back toward the source from the object.
- the transmission x-ray signature of organic materials is relatively weak in comparison to that of higher density, higher atomic-number materials such as metals. Since the x-ray transmission image is a result of interactions throughout a path through the entire object, larger and more complex objects such as cargo containers produce more confusing transmission images. Under these circumstances, even the presence of small amounts of metal and normal expected organic materials can produce extremely cluttered images masking the sought-for contraband. Image interpretation then becomes an overwhelming task. Frequently, most of the useful information is obtained from the backscatter image alone.
- the cargo container inspection device uses flying-spot x-ray imaging and backscatter imaging technologies. Equipment costs can be reduced if backscatter imaging is used to the exclusion of other modes of x-ray interrogation of the contents of the cargo container.
- FIG. 2A a perspective view is shown of a cargo container inspection system, designated generally by numeral 20, in accordance with a preferred embodiment of the invention.
- Cargo container inspection system 20 is shown deployed for inspection of passenger cars 22 and 23.
- FIG. 2B shows a preferred embodiment of the invention.
- a truck 24, typically 35' long ⁇ 8' wide ⁇ 10'6" high houses and supports the x-ray inspection equipment, ancillary support and analysis systems, and a hydraulic slow-speed drive mechanism to provide the scan motion.
- Truck 24 serves as both the platform on which the mobile system is transported to its intended operating site, and a bidirectional translation stage, otherwise referred to herein as a "bed,” to produce the relative motion required during a scan.
- Chopper 26 is used, in accordance with flying spot generation techniques known to persons skilled in the art, to scan beam 28 of penetrating radiation recursively in a vertical direction. Radiation scattered by the contents of the cargo container, shown here as passenger car 23, is detected by x-ray backscatter detectors 30. Boom 32 allows beam stop 34 to track beam 28 as truck 24 advances in scanning past the cargo container. Beam stop 34 is also referred to as a "beam catcher.” In addition or alternatively to beam stop 34, an x-ray transmission detector may be mounted in opposition to beam 28, tracking beam 28 on the distal side of the scanned cargo container.
- FIG. 3 a top schematic view of the layout of the system shown in FIG. 2B, is depicted as configured for transport.
- FIG. 4 is the corresponding side elevation, additionally showing the detectors in one of two available deployed positions.
- the modular components comprising the cargo container inspection system are: the penetrating radiation source assembly 40; x-ray high voltage generating subsystem including high voltage power supply 42 and high voltage tanks 44; backscatter detector modules 30, comprised of an upper bank 46 of detectors and a lower bank 48 of detectors; detector electronics module 50; and operator's console 52.
- the dashed position of upper backscatter detector banks 46 indicate the position for inspection of cargo containers.
- the x-ray source 40, high-voltage power supply 42, and positive and negative high-voltage tanks 44, are all in accordance with ordinary practice in the art of x-ray generation.
- a 450 kV x-ray tube is employed.
- FIG. 5A shows a cargo container inspection system 20, in accordance with a preferred embodiment of the invention, as deployed for inspection of a full-sized tractor-trailer 60 while FIG. 5B shows the same cargo container inspection system 20 deployed for inspection of a passenger van 62.
- the angle of elevation 64 of the 43° scanning beam can be changed depending upon the application. For optimum versatility, the range of limiting angles extends from at least 55° below horizontal to 55° above horizontal. This corresponds to an angular adjustment of the source axis from -33.5° to +33.5°.
- one side of a large truck 60 (up to 14' height), as depicted in FIG. 5A, can be completely covered in three passes; however, in many cases, satisfactory coverage can be achieved in two passes.
- the system operators must choose between doing a third pass or tolerating a small amount of corner cutoff 66, in which case, higher inspection throughput can be achieved. Since the scanning system is bi-directional, alternate passes can be in the forward and reverse directions.
- one-side of passenger cars and small trucks is scanned in a single pass of the system.
- the upper set 46 of backscatter detectors can be deployed over the top of smaller vehicles as shown in FIG. 5B, substantially improving the scatter collection efficiency and producing higher quality images.
- Backscatter detector modules 46 and 48 two are typically 6' long and 1' wide, and each typically comprises four segments.
- the cargo container inspection system has two scan-speed modes: nominally 3 inches/sec and 6 inches/sec.
- the faster speed results in higher throughput, the slower mode--higher image quality.
- image data in either mode is acquired into a 1024 ⁇ 4096 ⁇ 12 bit image memory and displayed onto a 1024 ⁇ 1024 high-resolution display via a continuously-adjustable 12-bit-to-8-bit look-up table. Additional displays can be provided to allow simultaneous viewing of more than one image, or, alternatively, images may be superposed or combined, as known to persons skilled in the art.
- Backscatter detectors are mounted to allow efficient collection of scattered radiation from close to the road surface, all the way to the roof of the inspected container.
- a motorized mechanism enables the upper set of detectors to be deployed over a small vehicle, as shown in FIG. 5B, though other means of deployment are readily apparent to persons skilled in the mechanical arts and are within the scope of the invention.
- the operator's console 52 (shown in FIG. 3), provides for the console operator to control the x-ray system and display images.
- Various display monitors may be provided.
- One preferred embodiment has an upper display for transmission images, and a lower display for the corresponding backscatter image.
- various display functions may be provided:
- Zoom, pan and scroll--Joystick controls allow the operator to display any part of the image at 2 ⁇ and 4 ⁇ magnifications.
- Continuous density expand-- This contrast-enhancing feature allows the operator to display any contiguous subset of the 12-bits (4096 digital intensity levels) of image data over the full black-to-white range of grey levels on the display monitors.
- the implementation is through a set of 10 pre-set push buttons, along with a trackball for fine-tuning.
- Edge enhancement--A mathematical algorithm sharpens the image and extends the effective dynamic range of the display for faster and easier image analysis.
- Reverse video--Operators may select between positive (black-on-white) or negative (white-on-black) image display, depending on personal preference.
- Image archiving--Operators may "mark and annotate" the images from the console keyboard, and store them on optical disk for future recall.
- Truck 24 containing cargo container inspection system 20 is fitted with a custom-built box (or truck body) 68 (shown in FIGS. 5A and 5B) specified to accommodate the imaging equipment, and to provide support structures, environmental control, and electrical power distribution.
- a custom-built box (or truck body) 68 shown in FIGS. 5A and 5B specified to accommodate the imaging equipment, and to provide support structures, environmental control, and electrical power distribution.
- Truck 24 is provided with both front- and rear-wheel drive: Standard rear-wheel drive from the truck's engine is used for normal over-the-road travel.
- An alternative drive mode is powered by a low-RPM hydraulic motor to obtain the very low speeds employed for the scan.
- the two drives are connected via a switchable gearbox to preclude the possibility of having both active at the same time.
- the hydraulic motor controls including speed selection, drive direction, and motion start/stop, are located in the cab of the truck under the control of the driver. As an additional safety feature, actuation of the truck's brake will automatically cause disengagement of the hydraulic clutch.
- a similar arrangement using a hydraulically-powered front or rear wheel drive is known in the art for other special applications requiring very slow vehicle motion.
- Deployable beam stop 34 is employed to assure compliance with FDA radiation safety requirements. However, the output radiation of the system is so low that the health and safety requirements for low radiation levels is met only a few feet away from the source even if no beam stop is used. Beam stop 34 uses a dense shielding material such as lead that is deployed from the end of a boom 32 that extends about 14' from the side of truck 24 at the location of the x-ray beam 28. Generation of x-rays is prevented by interlock circuits unless boom 32 and beam stop 34 are properly deployed.
- the beam stop is retracted into the hollow boom 32.
- Boom 32 is then rotated parallel to the truck axis and lowered into a cradle in truck box 68.
- the scan motion is exceedingly slow--1/3 to 1/6 of a mile per hour.
- An audible alarm is actuated whenever the scan drive mechanism is engaged for motion in either direction. Since this motion also coincides with x-ray generation, the audible warning also provides an "X-RAYS ON" warning.
- the x-ray high voltage power supply 42 is interlocked so that it cannot be energized unless both chopper wheel 26 is up to speed and truck 24 is in motion. This additional safety precaution ensures that the scanning beam will not be stationary over any one region of space for a long time, thus ensuring low delivered dose.
- the operators Upon arrival at the intended inspection site, the operators will first assure that the site is suitable: i.e., that there is a sufficient space available for system operation and that operating space can reasonably be secured for safe operations. They will then position the truck at the starting position for the first scan, assuring that there is sufficient room to move the truck ahead for the required scan distance, usually about 65 feet. (Scans will normally alternate, forward and back; it is also possible to scan sequentially in the forward direction only, to scan a continuous line of parked vehicles for example, provided that the necessary space is free.) Once positioned, the on-board generator is started to provide power for system operation, lighting, and a cooling unit. Operator's console 52 is powered up at this time.
- the beam stop is deployed by rotating the boom into a position orthogonal to the truck, and then lowering the beam stop out of the boom to its preset limit. This action closes an interlock circuit that is required before x-ray generation is possible.
- An x-ray tube warm-up sequence, if necessary, is then initiated from operator console 52.
- the physical configuration of the system setup is completed by rotating the x-ray beam angle to the direction (elevation) required for the intended scan operations. This is done by a manually-actuated electric motor, and with the aid of an indicator gauge to assist in setting the desired scan elevation. Scanning operations can then commence.
- Scan operations are simple and straightforward.
- One or more vehicles are directed to positions along the scan path (up to 65 feet of total vehicle length may be imaged in a single scan) and the drivers and passengers exit the vehicles.
- the system's computer is readied for image acquisition. This places the computer and data acquisition electronics into a status wherein c-rays will be initiated and image acquisition started upon receipt of a "scan" command initiated by the system's slow-speed drive controls.
- the computer also transmits a "ready" status signal to the scan drive control located next to the driver of truck 24.
- the driver sets the desired scan speed and direction at the scan drive control. After the "ready" status is received from the computer, the driver starts the scan by pushing a "start” button and releasing the truck brakes. "Start” initiates motion via the slow-speed drive. The driver has continuous control over the truck. He is responsible for steering, and may stop the truck at any time by actuating the brake. Otherwise, the scan will stop automatically after a full data set has been acquired by the computer (and the "ready" status is removed).
- a "scan" signal is sent to the computer.
- the computer then triggers the x-ray generator to ramp up to its pre-set operating conditions, and upon confirmation that they have been reached (about 5 seconds later) it starts data acquisition. Data acquisition continues until either the "scan" command is interrupted or the image memory is full.
- the intensity of the transmitted x-ray beam may be measured by a single, elongated transmission detector located on the opposite side of the inspected object from the x-ray source and carefully aligned with the plane of the x-ray beam.
- the detector is designed to accept and respond to x-rays striking anywhere along the length of its linear entrance slit.
- the detector is oriented so that the flying-spot beam sweeps repetitively from end-to-end along the slit while truck 24 moves past the inspected object.
- the detected signal is amplified, integrated, sampled and digitized into an image memory over many sequential, short time intervals during each sweep of the pencil beam.
- Each such digitized sample forms one pixel of the final image, and the series of samples acquired during one sweep of the beam constitutes one line of image data--typically 1024 samples per line.
- a complete image frame is constructed by acquiring successive lines as the object is moved through the scan plane.
- the positional image information is acquired by correlating the instantaneous detector output with the position of the flying-spot beam at that instant of time.
- a corresponding "fanbeam" system an entire line is illuminated at once and individual pixels along the line are acquired either by a large number of discrete detectors arranged along the line, or one or more detectors with positional sensitivity.
- the transmission detector may comprise scintillators optically coupled to photomultiplier tubes. This method is more efficient and less noisy than using a photodiode array. The resulting improvement in signal/noise allows equivalent images to be made at lower doses and with lower beam energies.
